Description

Technical Field

[0001] This invention relates to the field of nozzle bag capping torque testing technology, and more particularly to a bag capping torque testing device. Background Technology

[0002] The torque value for locking and opening bottle caps relative to spouts or bottle openings in packaging products is one of the key process parameters that need to be controlled. Whether the torque value is appropriate has a significant impact on the intermediate transportation of the product and its final consumption. (If the torque is too small when locking the packaging product, leakage is likely to occur during transportation. If the torque is too large when locking the packaging product, it will make it difficult for consumers to open and affect the use.) Therefore, it is often necessary to conduct sampling inspections using a torque detection device after the spout bags are produced.

[0003] Currently, existing cap torque testing devices, such as Chinese Patent Publication No. CN219265566U, disclose a precise bottle cap torque tester, including a tester body and a worktable mounted on the tester body. The worktable is equipped with left and right clamping components and front and rear clamping components for fixing the bottle body. The center lines of the left and right clamping components are perpendicular to the center lines of the front and rear clamping components. A touchscreen control panel is located on the front end of the tester body. The left and right clamping components fix and limit the lower part of the bottle body, while the front and rear clamping components fix the upper part of the bottle body. The device is designed to secure the spout pouch, but it is not very reliable in fixing the pouch. Most spout pouches on the market are of two types: small-capacity pouches with only one seal on each side and large-capacity pouches with two seals on each side. The device is not designed to be a single type of pouch and lacks a specific fixing method. To achieve a stable fixation, a large amount of pressure needs to be applied to the pouch. This can cause measurement errors and may also cause the liquid inside the pouch to splash out after the cap is opened, making it inconvenient to use.

[0004] How to quickly and stably secure the spout pouch, reduce pressure on its soft parts, prevent liquid from splashing out after unscrewing the cap, and make it easy to adjust and widely applicable, has become a technical problem that needs to be solved.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0010] When securing a small-capacity spout bag, use the two movable clamps in the middle to hold the side seals of the small-capacity spout bag. When securing a large-capacity spout bag, use the movable clamps on both sides and the fixed clamps to simultaneously secure the two side seals of the large-capacity spout bag.

[0011] According to the bag opening screw cap torque detection device of the present invention, each of the clamping bars is provided with a curved positioning part for accommodating the mouthpiece of the suction bag. Each positioning part is elastically connected to a clamping block at one end near the mouthpiece of the suction bag. Each of the clamping bars on both sides is elastically connected to a top bar. A locking rod is symmetrically passed through one of the clamping bars, and each locking rod is threaded to the other clamping bar.

[0012] According to the bag opening cap torque detection device of the present invention, each of the mounting platforms is provided with a limiting groove, and each of the clamping bars is slidably provided with a limiting post that cooperates with the limiting groove. Each limiting post is slidably disposed in the limiting groove, and each of the limiting grooves is symmetrically provided with a positioning hole. Each of the limiting posts is symmetrically elastically connected with a positioning head that cooperates with the positioning hole.

[0013] According to the bag opening screw cap torque detection device of the present invention, each of the sliding strips is provided with a plurality of positioning holes, and each of the uprights is symmetrically and elastically connected with positioning heads that cooperate with the positioning holes.

[0014] According to the bag opening screw cap torque detection device of the present invention, the end of the positioning head away from the positioning hole is inserted into the upright, the positioning head inside the upright is symmetrically provided with insert blocks, the upright is provided with slots that cooperate with the insert blocks, the insert blocks are slidably disposed in the slots, and elastic elements are provided between the positioning head and the upright.

[0015] According to the bag opening screw cap torque detection device of the present invention, each of the sliding strips is provided with a relief groove at the center, and each of the side fixing members is provided in the relief groove.

[0016] According to the bag opening cap torque detection device of the present invention, the outside of each upright is fitted with an elastic sleeve.

[0017] According to the bag opening screw cap torque detection device of the present invention, each of the fixed clamping plates is provided with a connecting strip, and both ends of the connecting strip are connected to the movable clamping plates on both sides of the fixed clamping plate.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0032] See Figure 1 and Figure 2This invention provides a device for detecting the torque of a bottle cap, including a torque detection device body 1. The torque detection device body 1 includes a detection platform 11 and a lifting cover 12. The lifting cover 12 is equipped with an assembly that can fix and rotate the bottle cap. During the process of rotating and opening the bottle cap, the torque is detected. Except for the structure on the detection platform 11 that fixes the spout bag (or bottle), the rest of the structure of the torque detection device body 1 is the same as the prior art. Its specific structure and working principle will not be described in detail here. The detection platform 11 is symmetrically equipped with movable moving platforms 2. A fixed platform 23 is provided between the two moving platforms 2. The fixed platform 23 can not only provide support for the spout bag (or bottle) but also make it easier for the operator to find the right position so that the bottle cap of the spout bag (or bottle) is directly facing the assembly that rotates the bottle cap inside the lifting cover 12. Each moving platform 2 is symmetrically equipped with a movable upright 3.

[0033] See Figure 1 and Figure 2 Specifically, the movable stages 2 are all rectangular structures. The two movable stages 2 are threadedly connected to the same adjusting rod 21. The adjusting rod 21 is rotatably connected to the fixed stage 23, and the internal threads of the two movable stages 2 are in opposite directions (the external threads on the adjusting rod 21 that mate with the two movable stages 2 are also in opposite directions). Both ends of the adjusting rod 21 are inserted into the fixed seats 111, and the fixed seats 111 are connected to the detection stage 11. The adjusting rod 21 is rotatably connected to the fixed seats 111. One end of the adjusting rod 21 is connected to the rotating block 211. By rotating the rotating block 211, the adjusting rod 21 is driven to rotate. Under the restriction of the detection stage 11, the movable stages 2 cannot rotate with the adjusting rod 21 and can only move towards each other on the detection stage 11.

[0034] See Figure 1 and Figure 2 Preferably, the rotating block 211 is provided with a rocker arm 212. The axis of the rocker arm 212 is not on the same straight line as the center of the rotating block 211, and the rocker arm 212 is rotatably connected to the rotating block 211. By shaking the rocker arm 212, the rotating block 211 can be driven to rotate, which makes it easier for the operator to operate.

[0035] See Figure 1 and Figure 2 Specifically, each of the moving platforms 2 is symmetrically provided with sliding grooves 22, and each of the uprights 3 is slidably disposed in the sliding grooves 22. Each of the sliding grooves 22 is rotatably connected to a rotatable drive rod 221. One end of each upright 3 inserted into the sliding groove 22 is threadedly connected to the drive rod 221. When the drive rod 221 is rotated, the upright 3 cannot rotate with the drive rod 221 due to the restriction of the sliding groove 22, and can only move horizontally on the moving platform 2.

[0036] See Figure 1 and Figure 2Preferably, each of the moving platforms 2 is symmetrically provided with a driving component 222. The output shaft of each driving component 222 passes through the slide groove 22 and connects to the driving rod 221. Each driving component 222 can drive the driving rod 221 to rotate, saving labor and making it easier to use the upright 3 to center, limit and fix the bottle or spout bag.

[0037] See Figure 1 and Figure 2 Preferably, each upright 3 is fitted with an elastic sleeve 31, which has a certain deformation capacity (e.g., a rubber sleeve). When fixing the bottle, the elastic sleeve 31 can better adapt to the shape of the bottle.

[0038] See Figure 1 and Figure 6 On two uprights 3 located on the same side of different moving platforms 2, the same sliding strip 4 is slidably provided. The sliding strip 4 can slide on both uprights 3 on the same side, and will not detach from the upright 3 unless it is removed from one side. Each sliding strip 4 is provided with several positioning holes 71. Each upright 3 is symmetrically and elastically connected with a positioning head 7 that mates with the positioning holes 71 (the end of the positioning head 7 away from the positioning hole 71 is inserted into the upright 3, and each positioning head 7 inside the upright 3 is symmetrically provided with a plug, and each upright 3 is provided with a slot that mates with the plug, and the plug is slidably disposed in the slot, and an elastic element 8 is provided between the positioning head 7 and the upright 3). When the sliding strip 4 stops sliding, the positioning head 7 mates with the positioning hole 71, thereby locking the position of the sliding strip 4. Each sliding strip 4 is provided with a relief groove 41 at the center, and a side fixing element 5 is provided in the relief groove 41. Each side fixing member 5 includes a rotating rod 51 threaded through the sliding bar 4. Each rotating rod 51 in the clearance groove 41 is rotatably connected to a mounting plate 52 (the friction between the mounting plate 52 and the rotating rod 51 is large, and the mounting plate 52 will not rotate arbitrarily without external interference). Each mounting plate 52 is symmetrically provided with a fixed clamping plate 521. Each side of the fixed clamping plate 521 is elastically connected with a movable clamping plate 53 (each fixed clamping plate 521 is provided with a connecting strip 531, and both ends of the connecting strip 531 are connected to the movable clamping plates 53 located on both sides of the fixed clamping plate 521. Each connecting strip 531 inside the fixed clamping plate 521 is provided with a slider. Each fixed clamping plate 521 is provided with a slide rail that cooperates with the slider. The slider is slidably set in the slide rail, and an elastic element 8 is provided between the slider and the slide rail). The two movable clamping plates 53 located between the two fixed clamping plates 521 abut against each other.

[0039] See Figure 1 and Figure 6Since the sides of most mouthpiece bags are divided into two types, one small-capacity mouthpiece bag has two pieces of material directly glued together and sealed, that is, there is only one seal on each side; the other is a large-capacity mouthpiece bag, which has two seals on each side, and there is a recess between the two seals on each side (the above two types of mouthpiece bags are mature existing technologies, and their specific shapes and manufacturing processes will not be described in detail here); when fixing the small-capacity mouthpiece bag, rotate the rotating rod 51 to adjust the position of the two side fixing parts 5, pull the movable clamps 53 on both sides of each side fixing part 5, the movable clamps 53 drive the connecting strip 531 to move, and at the same time squeeze the elastic part 8 at the connecting strip 531, thereby driving the two movable clamps 53 on each side fixing part 5 to abut against each other in the middle. 3. Place the side seal of the small-capacity mouthpiece bag between the two movable clamps 53 to fix the side seal of the small-capacity mouthpiece bag. When fixing the large-capacity mouthpiece bag, rotate the rotating rod 51 to adjust the position of the two side fixing parts 5, pull the movable clamps 53 on both sides of each side fixing part 5, and at the same time insert the two fixed clamps 521 on each side fixing part 5 into the recess between the two side seals of the large-capacity mouthpiece bag. Place the two side seals of the large-capacity mouthpiece bag into the gap between the movable clamps 53 and the fixed clamps 521 on both sides of each side fixing part 5, release the movable clamps 53, and fix the two side seals of the large-capacity mouthpiece bag at the same time using the movable clamps 53 and the fixed clamps 521.

[0040] See Figure 1 and Figure 6 Each upright 3 has a mounting platform 32 at the end furthest from the moving platform 2. A clamping strip 6 is slidably mounted on the mounting platform 32 of each of the two uprights 3 on each moving platform 2. The clamping strip 6 has a curved positioning part 62 in the middle to accommodate the mouthpiece tube opening. A clamping block 63 is elastically connected to the end of the positioning part 62 closest to the mouthpiece tube opening. Top strips 64 are elastically connected to the clamping strips 6 on both sides (the connection method between the top strips 64 and the clamping strips 6 is the same as the connection method between the positioning head 7 and the upright 3). (The specific structure and working principle will not be described in detail here.) One of the clamping bars 6 is symmetrically equipped with locking rods 65, and each locking rod 65 is threaded to another clamping bar 6 (the other clamping bar 6 is symmetrically equipped with locking holes that cooperate with the locking rods 65). The two clamping bars 6 are brought close to each other, and the locking rods 65 are used to increase the tightness between the two clamping bars 6. At the same time, the clamping blocks 63 clamp the mouth of the mouthpiece bag, and the top bar 64 clamps the sealing edges on both sides of the mouthpiece bag, thereby fixing the mouthpiece bag.

[0041] See Figure 1 and Figure 6Preferably, each mounting platform 32 is provided with a limiting groove 321, and each clamping bar 6 is provided with a limiting post 61 that cooperates with the limiting groove 321 (each clamping bar 6 is provided with a receiving groove that allows the limiting post 61 to slide). The limiting post 61 is slidably disposed in the limiting groove 321, and each limiting groove 321 is provided with a positioning hole 71 symmetrically. Each limiting post 61 is symmetrically elastically connected with a positioning head 7 that cooperates with the positioning hole 71 (the connection method between the positioning head 7 and the limiting post 61 is the same as the connection method between the positioning head 7 and the upright 3, and its specific structure and working principle will not be described in detail here). This prevents the clamping bar 6 from moving when it is not moved.

[0042] See Figure 1 and Figure 6 Specifically, each clamping block 63 is connected to a limiting rod 631 at one end near the clamping strip 6. The limiting rod 631 is elastically connected to the clamping strip 6 (the connection method between the limiting rod 631, the clamping strip 6, the connecting strip 531, and the fixed clamping plate 521 is the same, and its specific structure and working principle will not be described in detail here). This can ensure the clamping force of the clamping block 63 and improve the stability of the clamping block 63.

[0043] See Figure 1 and Figure 6 Preferably, the elastic element 8 is a spring, which provides return power.

[0044] See Figure 1 and Figure 6 Preferably, the drive component 222 is a rotary motor that provides power to the device.

[0045] See Figure 1 and Figure 6 When using the spout bag, place it on the fixing platform 23, ensuring that the spout bag opening is aligned with the rotating bottle cap assembly inside the lifting cover 12, with the two clamping bars 6 close to each other, and connect the locking rod 65. Use the clamping block 63 to clamp the spout bag opening, and the top bar 64 to clamp the sealing edges on both sides of the spout bag opening, thus completing the fixing of the opening first.

[0046] If the spout bag is a small-capacity spout bag, adjust the position of the side fixing piece 5, pull the movable clamps 53 located on both sides, place the side seal of the small-capacity spout bag between the two movable clamps 53, and use the two movable clamps 53 to fix the side seal of the small-capacity spout bag.

[0047] If the spout bag is a large-capacity spout bag, adjust the position of the side fixing member 5, pull the movable clamps 53 located on both sides, and at the same time insert the two fixed clamps 521 on each side fixing member 5 into the recess between the two sealing edges on the side of the large-capacity spout bag. Place the two sealing edges on the side of the large-capacity spout bag into the gap between the movable clamps 53 and the fixed clamps 521 on each side fixing member 5, and use the movable clamps 53 and the fixed clamps 521 to fix the two sealing edges on the side of the large-capacity spout bag at the same time.

[0048] When fixing the bottle, place the bottle on the fixing platform 23, ensuring that the bottle opening is directly opposite the rotating cap assembly inside the lifting cover 12. Move the clamping bar 6 and the side fixing member 5 away from the center of symmetry (the side fixing member 5 retracts into the clearance groove 41) to avoid the clamping bar 6 and the side fixing member 5 affecting the fixing of the bottle. Adjust the position of the upright 3 and use the elastic sleeve 31 to fix the bottle. If the diameter of the bottle is small, the clamping bar 6 can also be moved, and the clamping block 63 can be used to clamp the bottle opening at the same time to further improve stability.

[0049] This invention provides a device for detecting the torque of a capping nozzle on a sippy bag. The device includes a support rod, clamping bars, and other components that work together to quickly and stably secure the sippy bag. It clamps only the nozzle and the sealing edge, reducing pressure on the soft parts of the sippy bag and preventing liquid from splashing out after the cap is opened. The side fixing components can differentiate between small-capacity and large-capacity sippy bags based on the number of sealing strips on the side, allowing for targeted fixation. This design is easy to adjust and has a wide range of applications. In summary, the advantages of this invention are: it can quickly and stably secure the sippy bag, reduce pressure on the soft parts of the sippy bag, prevent liquid from splashing out after the cap is opened, and is easy to adjust, making it widely applicable.

[0050] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
